To all whom z't may concern:

Be it known that I, EDWIN E. ARNOLD, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have made a new and useful Invention in Retainers for Roller Thrust-Bearings, of which the following is a specification.

This invention relates to retainers for roller thrust bearings and an object is to provide a simple, lrelatively cheap.A and efiicient retainer.

be attain in the device This, as well as other objects which willv apparent to those skilled in this art, I

described in the specifithe drawingsaccompanying and forming a part of this application. p

In the drawings, Figure 1 is a view partially 'in end elevation and partially in section of a device embodying this invention, Fig. 2 is an edge of said device, Fig. 3 is a cross sectional view of a fragmentary portion of the device and Figs. 4, 5, and 6, are views in cross section illustrating dierent types of retainingrings -capable of being utilized in this invention.

The retainers consist of an annular ring 7 which in its preferred form has radially ex# tending holes drilled thereinto from the outer periphery as shown at 8, Fig.` 3. These holes are of slightly greater diameter than the diameter of rollers 9 adapted to lie therein so as to project laterally beyond each side face of the retainer as shown in Figs. 2 and 3. Two or more rollers may be placed in each of the roller pockets or holes if desired. The outer periphery of the retainer is provided with a centrally located groove 10 and a -'metal retaining band 11 machined view partially in sectionsaid ring and between said roller to snugly fit the outer metal is forced into groove 10 between holes 8. In Fig. 5 another type of ring having a reduced central web is shown and in Fig. 6 a ring is shown which is rolled out of sheet metal so as' to provide a centrally located relatively thin web.

Having thus described my, invention what I claim is- 1.- A retainer for roller end thrust bearings, comprising an annular Jring. providedwith radially extending roller pockets or channels and a circumferential groove, rollers within said channels and extending laterally therefrom, anda retainer band fitting pockets Patented nec., 9, 1919.;

periphery of retainer I `7 surrounds the retainer and at its center,

6. In Fig. 4: the band being depressed into said circumferential groove.

2. A retainer for roller end thrust bearings, comprising an annular, ring having a circumferential groove and roller pockets 0r channels drilled thereinto from the outer circuniference so as to extend radially of said ring, rollersin said pockets and a retainer ring provided with a relatively thin central portion and which between Said pockets is V depressed into said groove. I In testimony whereof I have hereunto subscribed EDWIN E. ARNQLD.

my name this 3rd day of July, 1918.
